amd64 and i386 are different platforms in the same sense that sparc64
and ppc are different platforms. An AMD 64 is not back-compatible to
pentium pro code when it's in 64-bit mode. Whilst 32-bit binaries can
be run on the amd64 platform, they need special handling, you can't
just mix-and-match world and kernel platforms.
